Prunedale's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Monterey County into its South-Central zone, the U-factor and SHGC target worth checking against any quote you get in Prunedale. Below that spec discussion sit 5 installers, their order set by Google rating, since Prunedale is outside this site's window license file. A high rating is worth a look, not a finished decision.

Prunedale's climate zone, in plain terms
Salinas, CA runs a January average near 51°F and climbs to about 63°F by July, a swing that adds up to roughly 2,830 heating degree days most winters, with 138 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Prunedale, separate from anything a brochure claims.
Zone 3C's requirement is the floor; Prunedale's specific load is what tells you whether beating that floor is worth the extra cost.
